Abstract
A coherent imaging system for producing high resolution images is provided. A coherent radiation source module produces two radiation beams, each at a different instance. An optical component directs the first radiation beam towards a target at a first angle to produce a first return beam, and also produces a first reference beam. Another optical component directs the second radiation beam towards the target at a second angle to produce a second return beam, and also produces a second reference beam. An aperture collects the first return beam and the second return beam. A detector module produces two coherent images based on interference between the return beams and the reference beams. The detector module also combines the first coherent image and the second coherent image to produce a high resolution coherent image, which has a resolution higher than a resolution of the first coherent image or the second coherent image.
